The proposed work can be achieved using following methodology.

3.1 Scripting

A scripting language or script language is a programming language that is used to manipulate, customize, and automate the facilities of an existing system. It is usually interpreted at runtime rather than complied. Scripting languages are also referred to as very high-level programming languages, as they operate at a high level of abstraction, or as control languages, particularly for job controllanguagesonmainframes.Inthiscontext,theterm script refers to a small program in such a language; typically,containedinasinglefile,andnolargerthanafew thousandlinesofcode.

3.1.1 Setting up a Controller and Pawn

The first step is setting up a controller and pawn.

3D Model Creating

Created 3D model of Indian architecture reminiscent of the iconic Red Fort (for Delhi Map) using Blender and UnrealEngine5.Initially,wegatheredreferenceimagesof the Red Fort from various angles to understand its intricate details using Google Earth. Then we set the scenes in Blender, we ensured proper scales and units.

Starting with a simple cube, we sculpted the basic shapes of the Red Fort, employing Blender's versatile modeling tools such as extrusion, scaling, and rotation. Adding architectural elements like arches, domes, and windows, we focused on maintaining accurate proportions and intricatedetailstoenhancerealism.Other3Dmodelswere also created like Road, Traffic Maintenance Models, Barriers,etc.

Creating the Level

By navigating through the menu, selecting "File," then "New Level," and then configured the various parameters of level like map size, type, spline type, etc. Utilizing the landscape tool, sculpted the terrain, ensuring it harmonized with our design concept by adjusting its size and shape accordingly. We also used Gaea for creating height-mapsofthedesiredlevel.

Using Quixel Bridge material and Gaea layered the different materials for various objects and ground. The material is layered so that it will show sedimentation of varioussoillayerswithheightmap.ThematerialsofTrees and their barks were set to give the Indian look to environment. The changes in texture and smoothness of ground are tempered to give the soil realistic look so that it will have more quality in players sight and will blur as thedistanceincreases.

3.5 Logic and Functionality

In game development, logic and functionality are the backbone of creating immersive and engaging interactive experiences. Logic encompasses the intricate set of rules and algorithms governing the behavior of the game, dictating everything from player input responses to win/loss conditions. Developers designed gameplay logic to ensure a seamless and enjoyable experience, scripting events, defining mechanics, and implementing artificial intelligence for lifelike character behaviors. On the other hand, functionality refers to the interactive features that bring the game to life, encompassing user interfaces, physics engines for realistic movement, sound and music integration, and networking capabilities for multiplayer experiences. Achieving a delicate balance between sophisticatedlogicandsmoothfunctionalityisessentialto crafting a successful game, where players are not only challenged by the intricacies of the game world but also seamlessly immersed in its interactive elements. Whether handling collision detection, character animations, or

multiplayer networking, the synergy between logic and functionality defines the essence of a well-crafted and enjoyablegamingexperience.

3.6 Integrating Model

Integrating models in game development involves the seamless incorporation of 3D or 2D assets, such as characters, environments, and objects, into the game engine. Models serve as the visual representation of the game'selements,contributingto the overall aestheticand immersive quality of the virtual environment. Game developers utilize modeling software, like Blender or Maya, to create these assets, considering factors such as polygon count, texture quality, and animation rigging. Once the models are crafted, they are integrated into the game engine, where their functionalities and interactions are defined through scripts and logic. The integration process also involves optimizing models for performance, balancing visual fidelity with the game's technical requirements.Successfulmodelintegrationisessentialfor delivering a visually captivating and coherent gaming experience, where the artistry and functionality of these digital assets converge to create a compelling and interactivevirtualworldforplayerstoexplore.

3.7 Testing and Debugging

In game development, the phases of testing, debugging, and deployment are integral to ensuring a polished and

stable gaming experience. Testing involves systematically evaluating various aspects of the game, including gameplay mechanics, graphics, and user interfaces, to identify and rectify potential issues. This process encompasses unit testing for individual components, integration testing to assess the collaboration of different elements, and user acceptance testing to gauge player experience. Debugging follows testing, addressing identified issues through the identification and correction of errors in the source code. Game developers employ debugging tools and techniques to enhance performance, fix glitches, and refine the overall functionality of the game. Once testing and debugging are satisfactorily completed,thegameisreadyfordeployment.Deployment involves packaging the finalized game for distribution acrossplatforms,ensuringcompatibilityandadherenceto platform-specific guidelines. This phase also includes considerations for marketing, release strategies, and ongoing support, marking the culmination of the development cycle and the transition to delivering the gaming experience to a wider audience. A thorough and well-executedtesting,debugging,anddeploymentprocess is crucial for releasing a high-quality and enjoyable game to players worldwide.
